Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627874, here are decompositions:

13 + 31627861 = 31627874
73 + 31627801 = 31627874
307 + 31627567 = 31627874
331 + 31627543 = 31627874
337 + 31627537 = 31627874
373 + 31627501 = 31627874
463 + 31627411 = 31627874
541 + 31627333 = 31627874

Showing the first eight; more decompositions exist.
